Just put the finishing touches on http://refzip.com and I need your feedback on functionality and design.
I think its a good effort. Design is also nice but results are similar to Google. Which API are you using?
The design looks nice and the results are okay as well. But I think that clicking links on search results should not be opened in frames on your site. I also want to know the script you're using. Is it a custom or purchased script? PHP or Python?
